Strategy An Irish based, multi-centre, international trial will be performed with the aim of comparing two treatment modalities for patients presenting with right colonic cancer. Pre-operative details, intraoperative findings and post-operative course will be prospectively accrued by the operating surgeon. Each surgeon has previous experience in performing this procedure and currently offer SILS colectomy to their patients outside of a clinical trial setting. All patients will be followed up and primary and secondary end-points will be recorded.
